Hacking Question about Save backups from a retail card...

[Solar12]

I got my SMT IV save dumped from my retail card, and would like to play the undubbed version which is a .3ds.
How do I get the .3ds to recognize my save?

I'm sure this has been asked before, but there are hundreds of topics about this and I don't have a lot of time to sift through them all, looking for the right answer.

Can anyone help?

I have Gateway by the way.

No one can help?
Just a quick link to a relevant tutorial would be enough.

Well, basically you have to do :
1- Boot NTR CFW with save manager plugin to backup an unencrypted version of your save.
2- In Gateway Mode create a save with the undub rom and backup it up with SaveDataFiler.
3- Replace userpart SDF backup with userpart NTR backup.
4- Import back save with SDF.
5- ...
6- Profit
